The relationship between nuclear power and nature is saturated with ambiguities and contradictions emerging from the different technological, scientific, and socio-cultural understandings of the two terms. Stemming from Nuclear Natures, an ongoing research project at Linköping University in Sweden, this article provides six takes—or briefs, as we call them—on nuclear natures in the form of analyses of environmentalist anti-nuclear campaigning, uses of natures surrounding operational nuclear power plants, nuclear waste management, and afterlives of denuclearised environments. The article supports the view that a type of situated environmental writing is called for in attempts to understand the disparate histories and futures of nuclear natures.
